STRATHMORE METEORITE, ESSENDY FRAGMENT

There are really three masses, the largest already referred to being ten

feet eleven inches long, six feet nine inches high, and five feet two

inches thick. It was called Ahnighito after the name of the daughter of

the explorer. The next larger mass weighing about three tons was named

“The Woman,” because the shape suggested the idea of a woman seated on

the ground with a babe in her arms and a shawl around her shoulders. The

third and smallest mass weighing about 1,000 pounds, was called “The

Dog,” and the three meteorites were known as a group to the Eskimo under

the name of “Saviksue,” or “The Great Irons.”

The Woman and The Dog were visited by Peary in 1894, and were obtained

the following year after much difficulty and exciting work, an incident

of which was the breaking up of the cake of ice on which The Woman had

been ferried from the shore to the ship, just as the mass was about to

be hoisted aboard. Fortunately there was enough tackle around the

meteorite to prevent its loss. In 1895 Commander Peary visited

Ahnighito, which lay on an island only four miles from the two smaller

masses, but he could do little toward its removal. The next year he made

another voyage for the purpose of getting the Great Iron, but was again

unsuccessful. This third attempt was made in 1897, when the meteorite

was brought in safety to New York in the ship _Hope_.

In the Foyer collection is also the famous Willamette meteorite, which

weighs more than fifteen tons. Its height is over six feet, its width

four feet, and its length ten feet. It is one of the most interesting

meteoric fragments in the collection, though not the largest.

Nevertheless, its appearance tells a wondrous story of the experience it

must have had during its swift rush through the air. The deep hollows in

its surface were probably caused by friction with the particles

encountered during its swift flight through the atmosphere surrounding

our planet. This resulted in the melting of part of the metallic

substance of which it is composed, chemical analysis showing that it

contains an admixture of iron, nickel, a small amount of cobalt, and in

addition some phosphorus and sulphur. To give an idea of the depth of

the hollows, the curator of the Museum showed the writer a photograph of

two boys seated in two of the largest.

The Willamette was discovered in the autumn of 1902, in the forest about

nineteen miles south of Portland, by a Welsh miner named Ellis Hughes.

At first he thought he had discovered an iron mine, but on digging away

the earth surrounding it, he found that it was a meteorite.

The miner, who was well acquainted with the handling of such masses,

constructed a low wooden truck, on to which he managed to overturn the

fifteen-ton mass, and then, with no other motive power than an old horse

windlassing a rope round a capstan as a winch, which had to be moved and

reanchored as the truck with its load was drawn up to it, he and his

fifteen-year-old son, working so quietly during the winter that not even

the nearest neighbor suspected what they were doing, dragged the mass

three-quarters of a mile on to his own land.

Apparently this mass of iron was known before the discovery above

related, as an Indian relic, revered from time immemorial by the Siwash

Indians. When the Portland Land Company, who owned the land on which the

meteorite was found, instituted legal proceedings in the matter,

claiming the right of possession, the lawyer engaged by Ellis Hughes to

plead his cause was of the opinion that the meteorite was not “real

estate,” but “discarded personal property,” belonging to whoever might

find it. In support of this statement he called a very old Siwash Indian

as a witness, who testified that the mass of iron had long been known to

members of his tribe, who attributed to it magic virtue. As a youth, he

said, he had been conducted to it by one of the medicine-men, and

informed that if arrows were dipped in the water which collected in the

hollows they would always wing their way to the heart of the game shot

at. However, the judge ruled that the meteorite went with the land, and

an order was issued giving possession thereof to the Portland Land

Company. It was purchased later on by Mrs. William E. Dodge, and

presented to the Museum of Natural History in New York City.

Near the Willamette meteorite is one called the Canyon Diablo, famous

chiefly on account of the fact that it contains diamonds. It was found

in 1891, near Coon Butte, Arizona, in the neighborhood of the town of

Canyon Diablo. The original size of the mass is not known, but thousands

of fragments have been collected, varying in weight from a fraction of

an ounce up to 1,087 pounds. More than sixteen tons of this material are

said to have been found within a radius of two and a half miles of Coon

Butte, a conical hill rising from 130 to 160 feet above the surrounding

plain, and containing a crater-like hollow about three-quarters of a

mile in diameter and probably originally 1,460 feet deep. The appearance

of this region seems at first sight, to the casual visitor, far more

suggestive of a terrific explosion at a remote period of the past,

resulting in an upheaval causing the vast crater from which the

meteoritic-looking masses scattered over the surrounding plain had been

ejected, but Dr. Hovey is of the opinion that their presence has been

caused by the downfall of an immense meteorite from above. According to

his investigations of the scene, “there is no lava of any kind in Coon

Butte or in its immediate vicinity, such as is found in volcanic

regions.” He also asserts that the main part of the mass has not yet

been discovered, the fragments so far found being only the portions

separated from the original mass during its passage through the

atmosphere and at the time of its impact with the earth. There are two

fragments of the Canyon Diablo meteorite in the Foyer collection, and

the largest piece discovered is the one weighing 1,087 pounds, to which

reference has already been made. A slice of the meteorite, in which a

diamond was found, undoubtedly attracts the greatest amount of attention

from visitors to the museum. “Diamonds falling from the sky,” they have

been heard to remark, “then why not make a search for the missing

fragment which may be a depository of unknown wealth?” However, the

possibilities are that it has buried itself to such a depth in its crash

to earth, that a search for it would be a stupendous undertaking, with

possibly no results as far as diamonds are concerned.

The importance attached to the discovery of diamonds in the Canyon

Diablo meteorite hinges upon the well-known fact that the diamond is the

purest carbon in nature. Charcoal is almost pure carbon, and, as

everyone knows, common charcoal is the product of combustion, the

residue from the burning of a piece of woody tissue excluded from the

air. This is the everyday teaching of chemistry in the college

laboratory. According to Dr. Hovey, regarding the fact that the Canyon

Diablo meteorite contains diamonds, “This gem-stone diamond has been

definitely proved to occur in only two meteorites, the other being a

Russian fall, although many masses are known to contain carbon in the

form of a soft, black powder.” The discovery of diamonds in Canyon

Diablo was made in 1891, by Professor G. A. Koenig of Philadelphia, and

was afterward confirmed by Dr. George F. Kunz of New York, Professor

Moissau of Paris, and other investigators. In 1905, Moissau dissolved a

fragment of Canyon Diablo weighing several pounds, and obtained not only

recognizable crystals of the diamond, but also crystals of a mineral

corresponding exactly in composition to the extremely hard artificial

silicide of carbon known as carborundum. The new mineral has been named

Moissauite, and this is the first time that it has been found in nature.

Geology teaches us not only that charcoal and the mineral coals are

different forms of that wonderful element we call carbon, but also that

bituminous and anthracite coals are the transformed products of ancient

vegetation, through the combined agencies of heat, enormous pressure,

and the slow transmuting effect of ages. This talismanic element is ever

found associated in some form with organic substance, and organic

substance is life substance, animal as well as vegetable.

Hence comes the all-engrossing conclusion that wherever carbon exists

there organic matter exists or has existed; and, if organic matter, then

its essential companion life! Does the meteoric fragment Canyon Diablo,

which fell from the sky upon our planet, come from a world now or at one

time the abode of life? Seemingly, we have drifted back to the original

argument, Did life first come to this earth in a meteor? and we are no

nearer a solution of the problem unless—as some one facetiously

remarked, an enterprising individual inclosed a message within a meteor

ere it took its departure for our planet from some distant world. As

Flammarion says in his book on _The Plurality of Worlds_: “The problem

remains the same. We want to know how life first appeared, and this

problem has not been advanced in the slightest degree by the theory

adopted by Lord Kelvin and Arrhenius.” But, as already stated, no one

dreamed of taking the suggestion made by Lord Kelvin, seriously.
